RESEARCH: "Approximately 5% to 10% of individuals with classic aniridia do not receive a molecular diagnosis after clinical testing for variants in PAX6 and its downstream regulatory region.
Objective: To apply optical genome mapping (OGM) and long-read whole-genome sequencing (lrWGS) to diagnose an individual with unexplained classic aniridia.
This diagnostic study aims to determine whether optical genome mapping and long-read whole-genome sequencing can identify a pathogenic structural variant disrupting PAX6 in an individual with classic aniridia after negative standard clinical and short-read genomic testing.
